高中物理是以学生感知的物理现象、理解的物理概念以及规律所遇到的各种不易预知的问题困难,而产生疑问以及引出了新问题.物理问题的解答不能等同于解数学问题,物理解题必须从物理概念出发,遵从物理规律.在这其中有许多物理量和零有密切关系,合理恰当地运用零的概念,往往使一头雾水的解题带来活力和解题生机. High school physics is based on the physical phenomenon perceived by students, the understanding of the physical concepts and laws encountered by the various difficult problems that are difficult to predict, and lead to new problems. The solution of the physical problems can not be equated with solving mathematical problems, physical solutions The questions must be based on the physical concepts and follow the laws of physics, in which many of the physical quantities are closely related to zero, and the reasonable and proper use of the concept of zero often brings the foggy problems to life and problems.
